Title: Power supply control system
Inventor: ONO SATOSHI
IPC: G05F1/455
Filed: 1983-08-02
Abstract: PURPOSE:To keep power supply constant even if the voltage applied to a load L is suddenly changed by controlling a load M exerting remarkable influence upon the voltage supplied to the load L by prescribed correcting data and then supplying electric power to the load L. CONSTITUTION:A CPU1 judges whether a heater 9 is to be controlled or not on the basis of a heater temperature signal from a heater temperature detecting circuit 10, and when judging no control, supplies electric power to a lamp 6 through a TRIAC control circuit 7 from the peak value of an AC power supply to a zerocross point on the basis of the detected data of a peak hold detecting circuit 5 and a zero-cross detecting circuit 3 because the voltage applied to the lamp 6 is not suddenly changed. At the control of the heater 9, previously fixed heater control correcting data are set in a timer 2 and a control signal is sent from the CPU1 to a solid-state relay SSR8. The SSR8 turns on or off the heater 9 at the zero-corss point of the AC power supply and then supplies electric power to the lamp 6 by using timer data keeping power supply to the lamp 6 constant.

Title: Reproducer for digital signal
Inventor: YOSHINAKA TADAAKI
IPC: G11B20/10
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to identify three values without being affected by fluctuation of level. SOLUTION: Edge signals U and D, which have the equal phase as the phase of the edge of a reproduced signal or are separated by one clock from the output of the integrated and equalized reproduced signal, are obtained. Based on the signals, the decoded binary-coded output for the reproduced signal is formed in an identifying circuit 30. Of the equalized waveform signals, which are obtained by equalizing the reproduced signal as the reference by partial responses (1, 1, -1, -1), (n) samples ((n) is the integer) are used, and judgment is performed with the identifying signal having the same phase as the edge phase of the reproduced signal as the reference. The detecting edge signal for the binary-coded output for the reproduced signal is obtained based on the result of the judgment. Since the detected edge signal for the binary-coded output is formed from the result of the operation at the levels at a plurality of the sample points, the identification is correctly performed, and the binary coding can be performed even when there are fluctuations at the reproducing level.

Title: Pulse gas laser device
Inventor: HOTTA KAZUAKI
IPC: H01S3/097
Filed: 1985-06-28
Abstract: PURPOSE:To obtain highly efficient laser light having a long pulse width, by connecting a saturable inductor to a peaking capacitor in series. CONSTITUTION:A saturable inductor 8 is connected to a peaking capacitor 5 in series. When energy is moved to a main capacitor 4 to the peaking capacitor 5, the saturable inductor 8 is in the saturated state. Therefore, the inductance Ls indicated by the saturable inductor is expressed by Ls=0. Therefore the inductance of a circuit ABCD is only an astray inductance Lo. The rise-up time of a voltage V3 becomes quick. When the energy is injected to a discharge space 3 from the peaking capacitor 5, the saturable inductor 8 is not in the saturated state and an inductance Lus is indicated. Therefore, the width of the pulse in the discharge current becomes long. The quickly rising voltage V3 is applied to discharge electrodes 1 and 2 and the discharge current becomes long. Therefore, the laser light having the long pulse width is obtained efficiently.

Abstract: PURPOSE:To contrive stabilization of product purity regardless of fluctuation in operating condition by seasons, days and nights, etc., by comparing detected purity values of O2 component gas before introduction into a product holder with the set value thereof and circulating the quantity according to the deviation to a pressure accumulation step when the former is low. CONSTITUTION:A valve 91 is closed to open valves 32 and 63 and an O2 compressor 61 is operated to discharge O2 component gas recovered in an O2 receiver 31 to a pipeline 6. When the purity of the O2 component gas is same as or higher than the set O2 purity value preset in a controlling means 92, the valve 91 is kept closed and the O2 component gas is then fed to a holder 7 and accumulated as product O2. When the purity of the O2 component gas is lower than the above-mentioned set value, the valve 91 is opened so as to provide an opening degree proportional to the deviation value and the O2 component gas in a volume corresponding to the opening degree is returned to the O2 receiver 31. Thereby the volume of the O2 component gas in the receiver 31 is increased and the gas is passed through a gas feed passage 5 for pressure accumulation and used as a pressure accumulating gas in an adsorption column 2 after desorption.
